Hair and Scalp Disorders (Trichology)

Hair and scalp disorders focus on the diagnosis, treatment, and prevention of conditions affecting hair growth, texture, and scalp health. Common issues include androgenetic alopecia, alopecia areata, telogen effluvium, hair shaft disorders, dandruff, seborrheic dermatitis, and scalp infections. This topic emphasizes the importance of a thorough clinical evaluation, including history-taking, scalp examination, trichoscopy, and laboratory investigations to identify underlying causes. Advances in treatment include the use of topical and systemic therapies, biologics, platelet-rich plasma therapy, hair transplantation techniques, and emerging regenerative approaches. Nutritional, hormonal, and genetic factors influencing hair health are also considered, along with patient counseling to manage expectations and improve adherence to long-term treatment plans. The discussion highlights the role of preventive care, early intervention, and multidisciplinary approaches involving dermatologists, endocrinologists, and nutritionists to optimize hair and scalp outcomes.
